l Biological Information

Biochem/Physiol Actions

α-Amylase hydrolyzes the α-(1,4) glucan ages in polysaccharides of three or more α-(1,4) ed D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose.

Application

α-Amylase is used to hydrolyze α bonds of α-ed polysaccharides, such as starch and glycogen. Product A1031 is from human saliva, is type IIA, and is supplied as a lyophilized powder. α-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis . α-Amylase from human saliva has been used to study the development of nutraceuticals, which may aid the treatment of diabetes and obesity .

Unit Definition

One unit will liberate 1.0 mg of maltose from starch in 3 min at pH 6.9 at 20 °C.
